Abstract

The SOCSIM micro-simulation model is used to investigate how kinship and family patterns in Britain changed as people passed through the ‘First Demographic Transition’, starting in the late nineteenth century, and the ‘Second Demographic Transition’, from the 1960s. Certain types of kin, such as former partners, became more common, and others, such as ever-born siblings, less so. An ageing of generational relationships is observed: events that formerly occurred early in life, such as the experience of one's parents' deaths, are being postponed. Patterns of re-partnering are leading to more partial relationships involving step- and supplanted parents, half-siblings, former partners and stepchildren.
